First In, First Out (FIFO) (layer costing) 
				
			
			
			
				
First In, First Out (FIFO) is an accounting method in which
					assets purchased or acquired first are disposed of first. FIFO
					assumes that the remaining inventory consists of items purchased
					last. FIFO is the most widely used method and also the most
					accurate method of aligning the expected cost flow with the actual
					flow of goods which offers businesses a truer picture of inventory
					costs. Furthermore, it reduces the impact of inflation, assuming
					that the cost of purchasing newer inventory will be higher than the
					purchasing cost of older inventory. Finally, it reduces the
					obsolescence of inventory.
